Frequency

Frequency, a critical concept in general imaging ultrasound, refers to the number of sound wave cycles per second, measured in Hertz (Hz). In medical imaging, higher frequencies offer superior spatial resolution, providing sharper, more detailed images of superficial structures like skin, muscles, and small vessels. Conversely, lower frequencies penetrate deeper into the body, making them ideal for visualizing deeper organs such as the liver, kidneys, and heart, albeit with reduced resolution. Choosing the optimal frequency is essential for accurate diagnosis, balancing image clarity with penetration depth to capture the best possible ultrasound image for various clinical applications. Understanding frequency is key for effective general imaging.
